Title: 66 Hertz Radiator
Post by: ChrisV289 on October 15, 2015, 08:57:36 PM

What should the engineering numbers be on the top of the tank of. A 66 Hertz car, automatic transmission? Also the approx date code as well on a car shipped to hertz around mid March. The top of the tank my dad currently has only the W MO but a date code of 4 66. No other numbers stamped.

That's it, same as my Oct 65 San Jose build 66 GT K Fastback with a C4, "W-MO" and dated "9 65". On mine the stamping reads upside down from the front.

So the engineering numbers found on 65 Mustangs was phased out?

Phased out in late 65 and on the W-MO radiators a soldered on tag with the engineering number . Dearborn and Metuchen had them metal stamped on the side straps.

The soldered on tag would read C4ZE-8005-M2 . You can get one from AMK and solder it on if missing.

Thanks Jeff, based on the VIN I gave you on his car, is the 12-65 the best date code to get or is there another in-between?

Since you have an automatic its going to make it allot easier (in comparison to manuals) so I would look for a 1-66 or even 2-66. Your VIN is right near the end of a group of a half dozen 1-66 radiator cars and before and just after a couple of 2-66 cars. Change is likely due to the fact that the cars were not (at San Jose either) order ;)

Believe 12-65 would be too early for yours

Thanks for sharing the partial VIN - makes these answers a whole lot easier to estimate
